Despite its massive popularity in web and microservices development, Spring Boot has its limitations. Most noticeably, long startup time, and high memory consumption. The root cause lies in how Spring relies on reflection to inspect classes, interfaces, fields, and methods at runtime. Is it possible to have the same productivity without the use of reflection at runtime?

Yes! Spring Native has the answer!

We are going to explore in this story how to integrate Spring Native into a Spring Boot microservice named customer-service, a simple CRUD application to manage customers. We are going to have two customer-service apps, one vanilla Spring Boot app named customer-service, the other, customer-service-native, a Spring Boot app with Spring Native baked in. We are going to take a close look at the performance boost Spring Native brings to Spring Boot.

Here’s a sneak peek of the startup time comparison between customer-service and customer-service-native.
